The Dump Barge Lummi Island is the little brother to the Liberty. With a 1,800 cubic yard capacity, the Lummi Island is the right size for an annual maintenance dredging project. A cost saver for the private land owner, the Lummi Island can be a perfect choice for your necessary dredging needs. Since the Lummi Island has a load line, it can perform work in Washington, Oregon, California and Alaska.
